Application filed June 13,

To all fio/tom t may. concern.'

Be it known that I, HERBERT W. Dunwga citizen of the United States, residing at Danville` in the county of Vermilion and State of Illinois, have invented new and useful Improvements in Molds, of which the following is a specification.

This invention relates to a. mold for relining. journal bearings, the generall object of the invention being to provide means for Walling in the concave face of the bearing so as to` leave a space for receiving the lining material.

Another object of the invention is to provide means for cooling the edges of the bearing while the same is being formed.

This invention also consists in certain other features of construction and in the Vcombination and arrangement of the several parts, to be hereinafter fully describedj illus# trated inthe accompanying drawings and specifically pointed 'out in the appended claims. l c

In describing my invention in detailn reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, andin which Figure l is a side view of the invention.

Figure 2 is a front view.

.Figure 3 is a planview. Y

'Figure 4l is a Asection on line- 4-4 of Figure 1. v

Figure 5 is a view of thepipes for the cooling fluid.

Figures 6 and 7 are detail views.

Figure 8 is a view of the false bearing.

Figure 9 is a view of the plunger 24.

In these views l indicates abase and 2 indicates a mold member which is bolted to the base, as shown at 3. The member 2 carries a pair of strips lwhich are vertically arranged and are spaced apart, the space between the strips being equal to the width of the lining to be formed.- 'Each `strip is prolvided with a longitudinally extending square passage 5 and its rear. face is provided with a longitudinally extending curved recess 6.

, These strips are held in place by the clamping strips 'i' which are bolted to the member 2 by the screw bolts 8. The upper ends the 'passages 5l are suitably connected with the Specification of Letters Patent.

pipes 9j said pipes being connected with horizontal pipes l() by the elbows ll and the pipes l0 being connected together by the T-coupling l2. This coupling receives the supply pipe 13 in which is located the control valve 14. The lower ends of the passages 5 are in communication with the curved con i duits l5 in the basewhich are in turn connected with the exhaust 16 in the base.

As shown in the drawings the member 2 is provided with longitudinal grooves 2 to receive portions of the strips l and l preferA to form these stripsintegral with the curved pipe l5 which forms the conduits l5. The base is grooved to receive this pipe. The strips and pipe can be slipped into place from the ltop and then'clamped in position by the strips 7. This arrange-- ment of parts will permit the pipes to be easily removed for the purposes of repairing the saine or replacing them by new ones. By making the member `the heat which is an advantage as if the member cooled too. quickly it would cause bubbles toappcar in the moulded' bearing.

Either water or compressed air can be circulated through the pipes parts. The journal part A is placed with the ends of its curved face against the strips 4` the flanges of the journal resti-ngagainst the edges of the ,clamping strips 7. Thus a for cooling the 2 solid 'it will hold space B is leftbetween the curved faceof the journal and the front part of member.l 2 into which the metal is to be poured to form the lining. As the metal is being poured the cooling fluid is caused to pass through the pipes and passages so as cool which in turn will cool the edges of the metal and the flow of this fluid is controlled by the valve 14. y

From the above it will be appa-rent that the lining is easily and quickly molded to .Y

which have openingsitherein which 'arefene p to keep the parts :f1

spring pressedy plunger 25, formed in the v eter ofthe shaft.

gaged by eccentric parts 2l on the shaft 22 which passesthrough the member 2. The shaft provided with a handle it may be rocked to cause its eccentric parts to reciprocate the hooks 20. @ne eccentric part is detachably securedtothe end of the shaft so as to permit the parts to be assembled;

ln order to with journals of varying sizes'l provide a 2e, seated in a bore member 2` and having its c urvedend engaging a part of shaft 22v so thaty said shaft is held against the far side of the opening 26 in theniember 2 in which the shaft is located and which is made considerable larger in diameter than the diam- Pins 27 are located in ,the vclamping plates 'Y and these pins engage projections ,20'v on the 'hooks 20, these parts being arranged to act as lguides for the hooks and permitting the hoolrs to drop into a vertical position vafter they have been moved "away from the journal.

`The clamping hooks not onlyy hold the Ajournal in proper position with respect to the ymold member l and its coolingv pipes but also releases the journal after the cast has been madeV and thejournal is froze to the moldmember las `the outward movement of the hooks will force the journal away from the mold memberdue to parts on the hooks striking the' ears lonthe journal. clamping movement of thehooks tends to force the journal down upon the bottom plate due to the downward movement of the hooks by the eccentric .parts on the shaft `as the hooks near the limit of their inward movement.

I also provide a false journal 28 for preheating the mold member 2' and its associated part, this false journal being so formed thatit will contact withthe .curved face'of the moldmember and will notleave, a space as the true journal-will. This false journal is made of 'cast iron or steel and is first heated before,v being placedl in position. After the mold is properly heated by, the heat from the false journal, this false journal is removed and the journal, to be refaced substituted therefor. j j It is thought from the `foregoing description that the advantages and novel features of my` inventionv will be readilyy apparent.

Vl'desire it .to be, understood thatfl. may makeA changes in the construction andin the y combination andjarrangement of the several parts, pro'videdthat such changes fall within the sco el of the appended claims.

3. mold ofthe class described comprising a base, arnold member secured thereto, vertically arrangedv strips on said member spaced apart a distance lequal'to the width of the lining to be applied to the journal, said .strips engaging the endsof the' curved face of thejournal, said strips having passages therein and means .for circulating a cooling fluid through said passages.y j
